摘要： A system and method for filtering signals in a communications system reduces hardware and chip size requirements by selectively connecting a filter along transmitter and receiver paths of a transceiver. In operation, a controller generated signals for connecting the filter along the transmitter path when the transceiver is in transmitter mode and for connecting the filter along the receiver path when the transmitter is in receiver mode. The controller then generates additional signals for setting one or more parameters of the filter based on the path connected, or put differently based on the operational mode of the transceiver. In a variation, the controller sets the parameters of additional elements coupled to the filter as a way of further controlling processing of the transmitter and receiver signals.

摘要： A variable-gain amplifier circuit uses a pair of single-ended operational amplifiers (100, 110) to amplify complementary portions of a differential input signal (IN, INB). By using two single-ended amplifiers (100, 110) instead of a single differential amplifier, linearity is significantly improved. In addition, common mode feedback circuitry is eliminated along with harmonic distortion and other forms of noise which tend to negative affect the quality of the signal output from the circuit.

摘要： An apparatus for oscillating a frequency, which comprises a phase lock loop, see fig. 5, a variable frequency divider() is shown, that divides a first frequency (Fout) signal by a division ratio to generate a second frequency signal, this based on a comparison of reference frequency clock input (Fref) and feedback input to phase/frequency detector (510). A charge pump (520) and loop filter (530) are shown with a divider (550) that divides the second frequency signal (355) to allow the correct feedback frequency to be realized. The VCO (540) inherently has a resonant circuit including the capacitors to be selected and a corresponding control voltage to set the frequency of operation as well as an active circuit (320) for proper gain.

摘要： A wireless receiver and a wireless receiving method are provided wherein a frequency of a radio frequency (RF) is down-converted into a frequency of a substantially zero intermediate frequency (IF) signal or a substantially low IF signal. The down-converted signal may be filtered by an integrated filter having a low quality factor and then up-converted again into a particular IF signal, thereby integrating an external element. For example, a receiving device may receive a RF signal in a required band. A frequency down-converting device may down-convert a frequency so that a center frequency of the RF signal becomes zero. A channel select filtering device may select a required channel from the signals whose frequency is down-converted. An IF signal converting device may up-convert a frequency of the channel selected signal into a required IF. An IF processing device may extract a baseband signal after the converted IF signal is inputted and processed. An amplifying device may amplify a signal with a gain required in a process of converting a frequency.
